Pacific Herring Spawn Index Data
Pacific Herring spawn index data for British Columbia from 1951 to present. Note that the spawn index is a relative index of spawning biomass. In addition, “NA" indicates that data are unavailable because they are either incomplete or withheld; contact the custodian for more information. For the "Region" column specifically, "NA" indicates that the location is outside stock assessment region boundaries. There are a few caveats to consider when interpreting Pacific Herring spawn index data, which are discussed in the technical report (see supporting documents).
